What I like about this time does the job perfect so far I have no complaints. I have tested it multiple times and gives a nice play Sound letting me know that there is a smoke around.

The WiFi Smoke Alarm with Replaceable Battery is a reliable and convenient option for home safety. Its compatibility with the Wisualarm Home Security App allows for easy monitoring and control from your smartphone. The T?V certification and compliance with EN 14604 ensure its quality and effectiveness. With its replaceable battery, you can trust that this smoke detector will provide long-lasting protection for your home. Overall, this 1-pack smoke alarm is a great investment for your peace of mind. We have fitted ours in the landing so far so good.

I bought one, and the battery stopped working after a month. After leaving a poor review the company offered to send me a replacement, which arrived yesterday. I have fitted it, so we'll see what happens this time, however I have altered my review as the customer service here was great, and I was very pleased they sent a replacement for the faulty one. They also offered a refund instead. Very happy with customer service by this company, and replacement came very fast too

Gut an dem einfach zu handhabenden Produkt ist auch, dass es eine austauschbare Batterie enth_lt. (Beim Vorg_nger mussten wir das ganze Ger_t einfach wegwerfen.)

Having built up a collection of electrical woodworking tools and a lot of timber as well, I decided a WiFi connected fire alarm was sensible.
Very easy to connect up with my mobile phone. It tested out well with the alarm in the workshop going off and a similar sounding warning coming on my phone.
